NEW - TTL Level Digital I/O

QMC mezzanine modules plug into a carrier card to interface connected I/O and provide a variety of signal processing functions. Acromag QMC470 modules offer 40 general-purpose, bidirectional I/O points to economically monitor and control a large quantity of digital devices. A PCIe bus interface provides communication to the carrier and host computer.

Each channel has interrupt capability for detecting change-of-state, positive (low-to-high) or negative (high-to-low) input level transitions. Debounce eliminates interrupts from noise and switching transients for error-free edge detection.
QMC470 outputs are full-featured. They provide closed-loop readback status monitoring. TTL level thresholds and 15mA sink capability allow a direct interface to standard relay racks. For safety, outputs go to a failsafe state upon power-up/reset without any instantaneous toggling to prevent false alarms.

Features
  • 40 bidirectional input/output channels
  • TTL-compatible inputs
  • CMOS-compatible open-drain outputs
  • Interrupt support for each channel
  • Programmable event interrupts (change-of-state, low-to-high, high-to-low)
  • Programmable debounce
  • Input hysteresis
  • Electronic overvoltage protection on individual channels
  • Software configured (no jumpers/switches) allowing “on-the-fly” changes without removing modules
  • Output readback registers – Eliminates the need for additional input channels to verify the output channel state
  • Extended temperature range and support for conduction-cooled systems

Acromag 		QPCe7210 Series - PCI Express Carrier Cards for QMC Modules PCI Express Carrier Cards for QMC Modules
QMC carrier cards provide an electrical and mechanical interface for QMC mezzanine modules. A QMC module plugs into the carrier card to interface connected I/O and perform a variety of signal processing functions. Acromag’s QPCe7210 carriers are PCIe expansion cards with a single QMC site and a high-density connector for field I/O signals. The QMC module’s PCIe bus interface routes to the carrier card edge connector for communication with the host computer... more
